[R] boxcox transformations

[Yogendra]

Hi,
I am new to R.
I need help with regards to box cox transformation.
I have phenotypic data for e.g. plant height.
data is non-normal. Skewness is 0.34.

Could you please help me?

[R] Weibull Distribution

[Yogendra]

Hi,

I want to estimate parameter of weibull distribution using mle for below
density function,
The PDF is,
f(x) = b a^-b x^(b-1)  exp -(x/a)^b  

In R ,density of the weibull distribution is,
f(x) = (a/b) (x/b)^(a-1) exp(- (x/b)^a)

which is different from my density,

I trying to estimate mle parmeter from R using fitdistr and fitdist
functions.
Can anyone tell me whatever parameter estimated from R are correct for my
density function or not?

Thanks 
Yogendra
